IMPROVEMENT IN MACHINES AFOR PLANING SHAVINGS FOR UPHOLSTERERS.

Specification forming part of Letters Patent No. 39,747, dated September 1 1863.

To all whom it may concern.-

Be it known that we, S. A; POST and W. H. POST, both of Durham, in the county of Greene and State of New York, have invented a new and Improved Machine for Manufacturing or Pla-ning Shavings for Upholstery Purposes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of our invention, taken in the line x m, Fig. 2; Fig. 2, a plan or top view of the same Similar letters of reference indicate `corresponding parts in the two figures.

This invention consists in the employment or use of a toothed cutter placed at right angles in a reciprocating bed, in connection with a planer, fitted obliquely in the same bed, the latter being placed on av suitable framing provided with a lever or clamp and a stop, and all arranged in such a manner as to cut shaviugs from wood in a proper manner for upholstery purposes.

To enable those-"skilled in the art to fully understand and construct our invention, we will proceed t o describe it.

A represents a framing, which may be constructedin any proper manner to support the working parts of the machine. In the upper part of the framingA there is placed a sliding bed, B, which has a reciprocating movement communicated to it by any convenient power. In this bed B there is fitted, at right angles, in a horizontal direction, a toothed cutter, (l, the teeth a. of which are formed by cutting rectangular notches b in the cutter at equal distances apart, the notches being equal in width to the teeth, as shown in Fig. 2. This cutter C is placed obliquely in a vertical direction in the bed B, and it is provided with a cap-plate, l), and secured in the bed by a wedge or key, E, like the iron of a joiners plane. In the bed B there is also tted a planer, F, which has an oblique position both in a horizontal and vertical direction, and a smooth cutting-edge. This planer is also provided with a cap, G, and is secured in the bed by a key or wedge, H, as shown in Fig. 1. The planer F is some distance back of the toothed cutter G.

I represents a stop, which is formed of a plate or board attached to the side bars, c c. This stop extends over the bed B at right angles thereto, and a rest or guide, J, is attached to one of the side bars, c, and abuts against one end of the stop I.

Kis alever attached to an upright, b, on the bolt, each tooth taking out a shaving, so that ridges will be left on the bolt between the grooves, and these ridges are taken oft' by the planer F, so that the bolt, after it passes the planer, is left with a smooth under surface. The oblique position of the planer causes the shavings taken ottl by it to curl. The width of the shavin gs takenoft' by both the toothed cutter and planer, it will be seen, is equal to the width of the teeth a of the cutter 0,-as the spaces between the teeth a are equal in width to the teeth, and shavings of any desired width may be out by employing a cutter, (l, provided with teeth a ot' a width corresponding to the desired width of the shavings.

The kind of wood usually employed for the purpose is hickory, but other tough elastic woods might answer a good purpose.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination of the toothed cutter C with the planer F, the above parts being iitted in a sliding or reciprocating bed, B, and used in connection withy a stop, I, and lever or clamp K, or their equivalents, all arranged substantially as and for the purpose specified.
